7 UK Myndigheder og BS/EN Vi fik en mail Det handler om vores engelske kollegaer der har udsendt et Safety bulletins (se filer) Jeg vil gerne høre din holdning eller historie til DS/EN :2014, afsnit , i forhold til valg af en egnet tryksikker forskruning (Ex d) for kabel indføring i en tryksikker kapsling (Ex d). HSE i UK har netop udsendt en Safety Bulletins i forhold til dette, hvor de anbefaler at man forholder sig til den informative anneks i BS/EN :2014 udgaven. Tillægget indeholder udvælgelsesproceduren, som den var i 2011 udgaven. Som du sikkert ved, så har DS/EN :2014 en ny holdning til valg af kabelindføring, i forhold til :2011 udgaven, når vi taler tryksikre kapslinger. Har du mulighed for at afklare hvorvidt DS er informeret omkring denne HSE og metoden for kabelindføring, som beskrevet i DS/EN :2011 udgaven?

8 UK Myndigheder og BS/EN Use of Barrier Glands in Potentially Explosive Atmospheres to meet IEC 60079: (Edition 5) Health and Safety Executive - Safety Notice Key Issues: There is currently a key difference between the current IEC : 2013 Standard and previous versions of BS EN : 2008 & IEC : 2007 for use of electrical equipment in potentially explosive atmospheres in that the IEC Standard currently allows the Duty Holder to use a standard Ex certified flameproof gland as opposed to a Ex certified barrier gland without the requirement to apply the previous flowchart used in the British Standard which identified glanding requirements based on gas group / zone / enclosure size. There is evidence that this approach creates a fire and explosion risk and this Notice provides Duty Holders with information on what action to take.

9 UK Myndigheder og BS/EN Action required: HSE recognises the risks identified by the BSI Technical Committee and also has further independent 3rd party evidence that supports the BSI s conclusions. In order to ensure that this risk is suitably controlled, the HSE has defined the Informative National Annex of BS EN : 2014 as an Established Standard (see PDF ) as it is considered to be a "published or commonly known standard of performance interpreted by HSE as a level of performance needed to meet a general or qualified duty under health and safety". Duty Holders should therefore apply the Informative National Annex of BS EN : 2014 as Relevant Good Practice when assessing the requirements for fitting a barrier gland to electrical equipment in potentially explosive atmospheres.

10 UK Myndigheder og BS/EN Baggrund UK S-udvalg ønsker Figur 2 fra ed. 4.0, som en del af standarden. De stemte imod standarden og får nu myndighederne til at intervenere via HSE. Paragraf UK stemmer NEJ til den seneste version af : The GB NC are extremely disappointed that it has to vote NEGATIVELY on this FDIS. It is deeply concerned that the revised procedure for the selection of cable glands into Ex d enclosures has been modified to such an extent that it contradicts the findings of the original 1970s research. No explanation has been given to NCs. The GB NC has commented on this matter at each stage of the revision process (CD, CDV and now FDIS) but its comments have been largely ignored. The GB NC believes the FDIS text is UNSAFE. Should the IEC and/or EN version of this standard go to publication then BSI will use GB comments as the basis of additional information which will be inserted into the National Foreword of any resulting British Standard implementation.

11 UK Myndigheder og BS/EN Baggrund The procedure given in the published edition of IEC (Edition 4) for the selection of cable glands into Ex d enclosures was based on research carried out in the 1970s by ERA in the UK. That research found that using an Ex d gland fitted with a compression seal, even if the cable was compact and circular, an ignition within an enclosure containing hydrogen (Group IIC gas) or repeated ignitions of other gases where the enclosure volume exceeded 2dm 3, resulted in the ignition of a surrounding flammable atmosphere. The ignition was caused by a cable sheath blow-out immediately outside the cable gland. Such blow-outs did not occur with gases of Group IIA or IIB where the enclosure was smaller than 2dm 3 or was only subjected to a few ignitions. The selection flow chart of Figure 2 was introduced to enable users to determine the correct type of Ex d cable gland (compression seal or barrier ).

12 UK Myndigheder og BS/EN Baggrund Start Yes Does this enclosure contain an internal source of ignition? a) No Yes Does the hazardous gas require IIC apparatus? No Use a suitable flameproof cable entry device with a sealing ring Apply d) or e) Yes Is the area of installation zone 1? No Yes Is the volume b) of the enclosure greater than 2 dm 3? No IEC 2696/02

13 UK Myndigheder og BS/EN Hvad er så sket Standarden blev i november 2013 stemt igennem i CENELEC med dette resultat:

14 UK Myndigheder og BS/EN Hvad er så sket Det Engelske Standardiseringsudvalg har derfor kontaktet Health and Safety Executive: HSE recognises the risks identified by the BSI Technical Committee and also has further independent 3 rd party evidence that supports the BSI s conclusions. Hvilket betyder at i UK skal det engelske tillæg anvendes, og at dette genindfører paragraf 10.4 fra den tidligere version med reference til tidligere udgivelser. Er det relevant? Er det den rigtige måde at gøre det på?

15 Deltagelse i udvalgsmøde Find ud af om deltagelse i et Standardiseringsudvalg i Dansk Standard er noget for dig mød de andre deltagere: Du kan deltage uforpligtende og gratis i et udvalgsmøde. Kontakt den udvalgsansvarlige, og hør om næste møde. S-531 holder møde den 12. maj 2016 i Roskilde

16 IEC Young Professionals 2016 Hvad er Young Professionals? The Young Professionals Programme brings together the world's upcoming expert engineers, technicians and managers. It provides them with more opportunities to shape the future of international standardization and conformity assessment in the field of electrotechnology.

17 IEC Young Professionals 2016 Hvad gør vi i Danmark? Workshop hos Dansk Standard den 20. juni kandidat udvælges til årets arrangement: IEC Young Professionals workshop will be held in Frankfurt, Germany, on 10 to 12 October, in parallel with the IEC 2016 General Meeting.
